Abstract: The disclosed embodiments provide a system that manages use of a solid-state battery in a portable electronic device. During operation, the system monitors a temperature of the solid-state battery during use of the solid-state battery with the portable electronic device. Next, the system modifies a charging technique for the solid-state battery based on the monitored temperature to increase a capacity or a cycle life of the solid-state battery. To modify the charging technique based on the monitored temperature, the system may increase a charge rate of the solid-state battery if the temperature exceeds a first temperature threshold. On the other hand, the system may maintain the charge rate of the solid-state battery if the temperature does not exceed the first temperature threshold.

Abstract: A rechargeable battery with an internal microcontroller, a memory and a temperature sensor. The microcontroller draws a current from the cells internal to the battery used to power device to which the battery is attached. Normally, the microcontroller, is in a first operating mode in which the microcontroller draws a relatively low current. During these periods the temperature sensor generates a signal representative of the temperature of the battery. When the signal from the temperature sensor indicates the battery temperature exceeds a threshold temperature, the microcontroller enters a second operating mode in which the microcontroller draws a relatively high current. While in the second operating mode the microcontroller records in the memory data regarding the fact that the battery temperature exceeded the reference temperature and the amount of time the battery was at a temperature above the reference temperature.
